This adds support to show firmware version information for both stored and
running firmware versions. The version and commit is displayed separately
to aid monitoring tools which only care about the version.

Example output:
  # devlink dev info
  pci/0000:01:00.0:
    driver fbnic
    serial_number 88-25-08-ff-ff-01-50-92
